package/harfbuzz: work around arc gcc10 bug

Browse Source 
With BR2_GCC_VERSION_ARC=y(arc gcc10) harfbuzz package exhibits a gcc bug
that makes build to fail. This bug is found only in official arc gcc10
provided by Synopsis, so we can't use the BR2_TOOLCHAIN_HAS_GCC_BUG_
approach since bug can't be even filed in gcc bugzilla.
To work around this, if BR2_GCC_VERSION_ARC=y we force using -O0.
